Centrifugal force: the component of apparent force on a body in curvilinear motion as observed from that body that is directed away from the center of curvature or axis of rotation.
The finite analytic method is used in the present study to calculate the turbulent flow field described with Navier-Stokes equations in body-fitted curvilinear coordinate system.
